WASHING-MACHINE.

Specification of Letters Patent.

Patented Jan. 22, 1918.

Application filed November 3,1916. Serial No. 129,387.

"To all whom it may concern:

Be it known that I, LAWRENCE W. MAM- MEN a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Washing-Machines, of which the following is a full, clear, and exact specification, as will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this, specification.

My invention relates in general to washing machines; and has reference more particularly to those machines of the dry cleaning type, in which gasolene or other similar fluids are employed in the cleaning operation.

The invention has for one of its principal objects to improve the construction and increase the efliciency and utility of machines of this character. Another object of my invention is the provision in such a machine of a double bodied structure embodying an outer hot water receiving compartment adapted for the external application of heat to the cleansing fluid in the inner compartment of such structure, and in a manner designed to eliminate any element of danger in the cleansing process. The invention also contemplates the provision of a novel frame support for said structure and of certain novel details of construction,

combination and arrangement of parts of the improved machine, whereby certain ad:

vantages are attained, as will be more fully described hereinafter, and pointed out in the claims.

These, together with such other objects as may hereinafter appear, or are incident to my invention, I attain by means of a construction illustrated in preferred form in the accompanying drawings, wherein:- v

Figure 1 represents a view in perspective of my improved washing machine;

Figs. 2 and 3 are respectively longitudinal and cross sectional views taken through the machine in Fig. 1;

Figs. 4 and 5 are perspective views of portions of the machine frame and body.

Referrin to the drawings, it will be seen that I provide a frame, A, comprising heads 6 and 7 spaced apart and connected by upper side bars 8 and lower side bars 9, the heads being provided with sockets 10 for the re ception of the upper ends of the supporting legs 11, which latter may be braced by the bracing rods 12.

Having bearings in the heads 6 and 7 of the frame is a rotary barrel 13 into which articles of clothing to be cleansed are placed, rotary movement being imparted thereto by the crank-wheel 14 through. suitable gearing such as the pinion l5 and gear wheel 16, respectively mounted on the spindles of the crank wheel and barrel.

Directly supported by the frame A is the body B of the machine, which body is preferably formed of galvanized tin and comprises an inner compartment 17 having side flap extensions 18 projecting upwardly beyond the upper marginal portions of its ends 19, and an outer compartment 20 spaced away from said inner compartment to provide a hot water receiving chamber 21 whose upper edge portions 2O are soldered or otherwise secured to the inner compartment 17 along a line just below the plane of the upper marginal portions of the end members 19. These said portions are bent inwardly and then upwardly to provide flanges 22.

The side edges of the flap extensions 18 are bent upon themselves to provide attaching portions 23, and the upper edges thereof are rebent as shown in Fig. 5 to form the channeled flanges 24.

In assembling the body B upon the frame A, the attaching flanges 23 are nailed or otherwise secured to the sides of the heads 6 and 7, with the flanges 22 fitting snugly into recesses 25 formed longitudinally in the under faces of said heads, so as to form a liquid-tight joint, and. when thussecured the flap extensions 18 rest against the side bars 8 and 9 with the channeled flanges 24 bearing against the top portions of the bars 8. In so forming the frame and body, manufacturing processes are simplified and synchronized to the extent, at least, that these parts may be respectively formed and shaped in difl'erent departments or shops and then readily assembled at another point into the complete body structure. As thus assembled a tight and well braced structure capable of withstanding hard usage is obtamed.

lhe numeral 26 designates the cover for closing the open top of the machine body, and through the open top articles of clothin are passed into the barrel and cleaning fiui introduced into the inner compartment 19,

within which the barrel has rotary move-.

ment. In order to increase the efficiency of the cleaning operation, hot water is introduced into the space 21 for externally heating the inner compartment l7, by means of a lip 27 formed in the upper portion 20 of the outer compartment and which is designed to communicate with the space 21 through a downwardly extending passage 27". As will be seen from an inspection of Fig. 2, the inner compartment is provided with an outlet cock and plug, indicated at 28 in this figure, which extend through the end wall of the compartment 20. This compartment 20 receives an adequate measure of support by arranging the brace rods 12 so as to abut against the lower side portions of the same, as in the manner shown in Fig. 3 of the drawings, and is also provided with an outlet cock and plug for the removal of the Water therefrom, the cock and plug being designated by the numeral 29, (Fig. 2).

lit will be obvious that the heads and compartments together constitute the body proper of the machine, and that the former, with the legs and their bracing rods, form the supporting means for said compartments. If desired, one of the heads may have secured to it a Wringer support 30.

As will be seen from an inspection of Figs. 2 and 3 the preferred construction of the lid 26 contemplates the provision of a thin flat metallic body portion formed therebelow at each side margin with divergent outer and inner flanges 31 and 31, each of said pair of flanges cotiperating to constitute a downwardly opening angular recessed member capable of receiving the corresponding angular portion of the top member 8 of the side frame. Underneath the flat end portions of the lid, which rest on the flat-topped heads, are brace bars 32 designed to have a snug fit within the heads when the lid is placed in position (Fig. 2), and these bars are terminally secured to the inner flanges 31' by any suitable fastening elements such as the nails shown. In this way a light but well braced cover is provided, and one that is particularly adapted for effective use in a body structure such as is herein shown and described.

From the fore oing description, the essential features and elements of my improved body structure, together with its simplicity and other advantages thereof, will be clearly apparent to those skilled in the art.

What I claim is 1. A washing machine body comprising in combination a frame unit embodying a. pair of heads and connecting side frame members, a barrel rotatably mounted in said unit and having a segmental section thereof depending beyond said heads, the latter having their lower faces terminating just below the axial line of the barrel, and a fluid container unit formed to receive said segmental section and comprising upwardly extending end portions associated with the lower faces of said heads and side portions provided with flap extensions bearing on said side mem bers and secured to the sides of said heads.

2. In a washing machine, the combination of a pair of heads and connecting spaced side frame members, a fluid container unit suspended therefrom comprising a metallic box-like body embodying vertically extending end portions adapted to marginally register with said heads and intermediate side portions terminally associated with said end portions, said portions constituting the container proper and said side portions formed with flap extensions projecting upwardly past said end portions to inclose said side frame members, means for securing said extensions against the sides of the heads whereby to afford a support for said body, and a barrel rotatably mounted in said heads and having its lower portion dependent within said box-like body and intermediate its said end and side portions.

3. In a washing machine, the combination of an upper frame unit comprising solid heads and connecting spaced side frame members associated with said heads, a barrel rotatably mounted in said heads, a lower container unit suspended from said frame comprising a metallic box-like body having vertically extending end portions adapted to marginally register with said heads and side portions provided intermediate'said end ortions with closure flap extensions exten ing upwardly therefrom past said end portions to rest upon and close in said side frame members, said flap extensions secured to the portions.

4. A washing machine body comprising in combination a frame embodying a pair of substantially vertically disposed heads and bers, and a barrel rotatably mounted adjaspaced connecting side frame members discent the base lines of said heads and havposed in the plane of the sides of said heads, ing a segmental section thereof depending 10 a fluid container suspended therefrom comin said container.
